+Found by looking at the decompiled Minecraft Classic source code in ClassiCube client.
+
+Note: All variable names were made up in the process of deobfuscating the code.
+
+Relevant variables starting values:
+bool applyBreakAnim = false;
+int breakAnimTicks = 7; //how many ticks it takes for the block break animation to complete. Never changes
+int breakTimer = 0;
+
+
+EVERY TICK:
+
+	Add 1 to breakTimer
+	If breakTimer is equal to breakAnimTicks, set applyBreakAnim to false and set breakTimer to 0.
+		
+	
+EVERY TIME YOU CLICK TO START THE ANIMATION (checked on tick):
+	breakTimer = -1
+	applyBreakAnim = true;
+	
+	
+	
+	
+
+EVERY FRAME:
+
+if applyBreakAnim is true...
+
+	creates an elapsedTicks, which is the current breakTimer plus delta
+	
+	creates lerp, which is elapsedTicks divided by breakAnimTicks
+	
+	creates sinHalfCircle, which is sin(lerp * PI)
+	
+	creates sqrtLerpPI, which is the square root(lerp) * PI.
+
+	Then, moves the block on...
+	X by -sin(sqrtLerpPI) * 0.4
+   
+	Y by sin(sqrtLerpPI * 2) * 0.2
+	
+	Z by -sinHalfCircle * 0.2
+	Note: Z should be forward/back in this case, if it isn't already in CS
+	
+end if.
+
+
+Intermission: SET HELD BLOCK POSITION AT THIS POINT
+
+
+if applyBreakAnim is true...
+
+	(There will be variable re-use from the first if statement in here.)
+							
+	creates sinHalfCircleWeird, which is sin(lerp * lerp * PI)
+	
+	rotates on Y axis by sin(sqrtLerpPI) * 80
+
+	rotates on X axis by -sinHalfCircleWeird * 20
+	
+end if.
+
+
+If it's not your hand, scale down by 0.4
+
+If it's your hand, set hand position here.
